public class NiceTitForTat_Offering
extends OfferingStrategy

This is the decoupled Offering Strategy for NiceTitForTat (ANAC2011). The code was taken from the ANAC2011 NiceTitForTat and adapted to work within the BOA framework. >>Extension of opponent model>> As default the agent implements a behavior when an opponent model is used and when not. The only extension we made is to allow to switch the opponent model. DEFAULT OM: ScalableBayesianModel
